    摘要： An apparatus and method for processing channel information in a broadcasting system for transmitting/receiving a cable broadcasting signal are disclosed. In particular, a headend which transmits a broadcasting signal and channel information transmits plural pieces of channel information having different sizes with respect to a single channel to broadcasting receivers. Each of the broadcasting receivers selects most suitable channel information from the plural pieces of channel information of the single channel and displays the selected channel information on a screen for the channel. Accordingly, it is possible to provide users with the channel information which can most accurately represent the contents of the displayed channel.

    摘要： An emergency alert message is included in a cable broadcast signal. The emergency alert message includes major and minor details channel numbers associated with a details channel. A details channel number is configured based on the major details channel number when the minor details channel number is set to a null value. Next, it is tuned to a channel frequency of a digital cable channel corresponding to the details channel number when the details channel number exists in a digital channel number list. Alternatively, the emergency alert message includes a details channel source field which indicates whether a details channel is a digital or an analog channel. Then, it is tuned to a channel frequency of one of a digital cable channel and an analog cable channel based upon a value of the details channel source field.

    摘要： A broadcasting receiver and method of interfacing resource information between a host device and a POD, sending host device resource information and obtaining host device resource information are disclosed. A POD sends a resource information requesting message. And a host device receives the resource information requesting message and responds with a resource information message including a resource identifier defined in a resource information table which includes information indicating whether the host device supports A-mode. Using a “conditional access” feature provided by a conventional cable security card, content received through any type of transport protocol (including an IP protocol) including a wired/wireless network can be protected and A-mode resource information can be systematically defined together with other-mode IP communication resource and the resource information of different modes can be integrated and transmitted to the host device.

    摘要： A host device interfacing with a point of deployment (POD) and method of processing broadcasting data are disclosed. An IP physical interface unit receives a frame including an internet protocol (IP) packet carrying broadcast data through a network modem. A routing engine routs the frame based on a destination information included in the frame. An IP to TS Decapsulator extracts a MPEG-2 TS packet from the IP packet included in the routed frame. And a multiplexer augments the extracted MPEG-2 TS packet with Packet Header carrying an identification information, multiplexes the augmented MPEG-2 TS packet and forwards the multiplexed MPEG-2 TS to the POD.
